scatterplot

By visual inspection, determine the best-fitting regression model for the scatterplot is Quadratic.
We are given the scatter plot representing data.
Now, it is required to find the best regression model for the scatter plot.
From the graph, we see that,
The scatter plot has a behavior similar to a quadratic equation.
That is, the graph is starting and ending in the same direction.
Also, the points in the scatter plot are increasing at first to reach a maximum value and then decrease.
Thus, we have, Visually the scatter plot represents a quadratic equation.
What is a Quadratic equation?
In algebra, a quadratic equation is any equation that can be rearranged in standard form as where x represents an unknown, and a, b, and c represent known numbers, where a ≠ 0. If a = 0, then the equation is linear, not quadratic, as there is no term.
